Latest Patents

Donald Pearce holds a patent for a method of measuring adjacent channel power. This invention involves down-converting a signal source from a transmitter by mixing it with a locally generated signal. The desired adjacent channel band is converted to base band, allowing for accurate measurement of adjacent channel power after filtering through a low pass filter. To overcome the notch in the filter characteristics that occurs during a.c. coupled measurements, the locally generated signal is modulated or swept around the center of the adjacent channel band. This innovative technique enhances the reliability of power measurements in complex signal environments.
